PHP adds keys to decoded and then encoded JSON data

Question

I\'m not sure why this is happening, but I seem to run into this problem often. Here is my original JSON for a shopping cart:

{
    \"cartitems\": [
                 


        

Answer 1

Try this, worked for me. Transfer the array to a new array with auto keys:

/* Remove the item */
foreach ($_SESSION['cart_items']['cartitems'] as $key => $product) {
    if ($product['cartid'] == $cartid) {
        unset($_SESSION['cart_items']['cartitems'][$key]);
    }
}
$var=array();
foreach($_SESSION['cart_items']['cartitems'] as $key => $product) {
        $var['cart_items']['cartitems'][] = $product;
}
echo json_encode($var['cart_items']);
